` and `<meta name="description">`** — per page if possible, at least the main layout/template. 2. **Open Graph tags** — `og:title`, `og:description`, `og:image`, `og:url`, `og:type`, `og:locale`. 3. **Twitter Cards** — `twitter:card`, `twitter:title`, `twitter:description`, `twitter:image`. 4. **Canonical tags** — `<link rel="canonical">` per page. 5. **`robots.txt`** — exists? Blocks important paths? 6. **`sitemap.xml`** — exists? Up to date? Referenced in robots.txt? 7. **Structured data (JSON-LD)** — any existing `<script type="application/ld+json">`? Which schemas? 8. **Heading hierarchy** — single `<h1>` per page? Logical nesting? 9. **Image `alt` attributes** — present on all `<img>`? 10. **`hreflang`** — needed if multilingual content detected. 11. **Internal linking** — navigation structure, orphan pages. 12. **URL structure** — clean, descriptive, no query-string routing. ``` SEO AUDIT FRAMEWORK : <name + version> RENDERING : <SSR / SSG / SPA / hybrid> TITLE/META : <status> OPEN GRAPH : <status> TWITTER CARD: <status> CANONICAL : <status> ROBOTS.TXT : <status> SITEMAP.XML : <status> JSON-LD : <status> HEADINGS : <status> ALT ATTRS : <status> HREFLANG : <status> INTERNAL LINKS: <status> URL STRUCTURE : <status> ``` ## STEP 2 — INTERVIEW (if needed) Some SEO decisions require business context that the code cannot tell you: target keywords, geographic scope, audience, competitors, business type. If $ARGUMENTS already provides this context (e.g. `"local SEO plombier 91 94 77"`), extract what you can and skip redundant questions. If critical info is missing, load and follow: `$HOME/.claude/agents/interviewer.md` **Questions to ask** (skip any answerable from the codebase or $ARGUMENTS — max 8 total, grouped by theme): **Business context** - What does the business do? (type, industry) - Who is the target audience? **Keywords & geography** - Primary keywords / phrases to rank for? - Geographic scope: national, local (which cities/departments)? - Local SEO needed? (physical address, service area) **Competition & goals** - Competitor URLs to benchmark against? - Priority: organic search, local pack, featured snippets? **Content** - Main languages of the site? - Blog / content marketing planned? After receiving answers, proceed to STEP 3. ## STEP 3 — FIX IN CODE Apply SEO fixes directly. Scope: **markup and metadata only**. Never modify business logic, layout, styles, or functionality. ### What to fix 1. **`<title>` + `<meta name="description">`** - Unique per page. Title: 50-60 chars. Description: 150-160 chars. - Include primary keyword naturally. 2. **Open Graph tags** (in `<head>`) ```html <meta property="og:title" content="..." /> <meta property="og:description" content="..." /> <meta property="og:image" content="..." /> <meta property="og:url" content="..." /> <meta property="og:type" content="website" /> <meta property="og:locale" content="fr_FR" /> ``` 3. **Twitter Cards** (in `<head>`) ```html <meta name="twitter:card" content="summary_large_image" /> <meta name="twitter:title" content="..." /> <meta name="twitter:description" content="..." /> <meta name="twitter:image" content="..." /> ``` 4. **JSON-LD structured data** — pick schemas based on context: - `Organization` — always, for the business entity. - `LocalBusiness` — if local SEO (address, phone, hours). - `BreadcrumbList` — if multi-level navigation. - `WebPage` / `WebSite` — for main pages. - `FAQPage`, `Product`, `Service` — if content matches. Place as `<script type="application/ld+json">` in `<head>`. 5. **`sitemap.xml`** — create or update. List all public URLs. For dynamic frameworks, prefer the built-in sitemap plugin (e.g. `next-sitemap`, `@astrojs/sitemap`). 6. **`robots.txt`** — create or fix. ``` User-agent: * Allow: / Sitemap: https://<domain>/sitemap.xml ``` Ensure it does NOT block CSS/JS needed for rendering. 7. **Canonical tags** — add `<link rel="canonical" href="...">` on every page. Self-referencing unless duplicates exist. 8. **`hreflang`** — add if multilingual content detected: ```html <link rel="alternate" hreflang="fr" href="..." /> <link rel="alternate" hreflang="en" href="..." /> <link rel="alternate" hreflang="x-default" href="..." /> ``` 9. **Heading hierarchy** — fix if broken (multiple `<h1>`, skipped levels). One `<h1>` per page containing the primary keyword. 10. **Image `alt` attributes** — add descriptive alt text to images missing it. Keep concise, include keyword where natural. 11. **Internal link suggestions** — add as code comments where relevant pages should cross-link: ```html  ``` ### Framework-specific notes - **Next.js**: use `metadata` export (App Router) or `Head` component (Pages Router). Use `next-sitemap` for sitemap. - **Astro**: use `<SEO>` or direct `<meta>` in layouts. Use `@astrojs/sitemap` integration. - **Nuxt**: use `useHead()` composable or `nuxt.config` meta. - **Static HTML**: edit `<head>` directly. - **React SPA**: flag that SEO is severely limited without SSR. Add meta tags via `react-helmet` but warn about SPA limitations in the report. ## STEP 4 — GENERATE SEO-GUIDE.md Create `SEO-GUIDE.md` at the project root with two sections. Be concrete: tools, URLs, step-by-step instructions. Mix French and English naturally where relevant (the user is French-speaking). ```markdown # SEO Guide — <Project Name> ## Quick Wins (< 1h each) ### Google Search Console 1. Go to https://search.google.com/search-console 2. Add property → URL prefix → enter your domain 3. Verify via DNS TXT record or HTML file upload 4. Submit your sitemap URL: https://<domain>/sitemap.xml 5. Check "Coverage" tab for indexing errors ### Google Business Profile (if local) 1. Go to https://business.google.com 2. Create or claim your business listing 3. Fill: name, address, phone, hours, categories, photos 4. "Plus ta fiche Google est complete, mieux tu seras reference" 5. Respond to every review — Google rewards activity ### Structured Data Testing 1. Go to https://validator.schema.org 2. Enter your URL → check for errors/warnings 3. Also test with https://search.google.com/test/rich-results 4. Fix any errors flagged in JSON-LD ### Canonical Verification 1. View source on each page → search for `rel="canonical"` 2. Ensure each canonical points to itself (no duplicates) 3. Check Google Search Console → "URL Inspection" for each page ## Strategic (ongoing) ### Backlinks - "Plus tu as de liens vers ton site sur le web, mieux c'est reference" - Register on relevant directories (Pages Jaunes, Yelp, etc.) - Guest posts on industry blogs - Partner cross-linking - Tool: https://ahrefs.com/backlink-checker (free tier) ### Local Citations (if applicable) - Ensure NAP (Name, Address, Phone) is identical everywhere - Register on: Google Business, Pages Jaunes, Yelp, Foursquare, local chamber of commerce - "Optimiser sa fiche Google" = keep it updated, add posts weekly ### Core Web Vitals - Monitor at https://pagespeed.web.dev - Key metrics: LCP < 2.5s, FID < 100ms, CLS < 0.1 - Fix: optimize images (WebP), lazy load below-fold, minimize JS ### Content Strategy - Blog with keyword-targeted articles (1-2 per month minimum) - Answer "People Also Ask" questions from Google SERPs - Use https://answerthepublic.com for content ideas - Internal link new content to existing pages ### Social Signals - Share every new page/article on social platforms - OpenGraph tags ensure proper preview cards (already set up) - Consistent posting builds domain authority over time ### GEO (Generative Engine Optimization) - Structured data helps AI engines understand your content - Clear, factual content with citations ranks in AI answers - FAQ sections are particularly well-suited for AI extraction ``` Adapt sections based on what's relevant to the project. Remove sections that don't apply (e.g. local SEO for a SaaS product). ## STEP 5 — REPORT Print a clear summary of everything done: ``` SEO ANALYSIS COMPLETE FRAMEWORK: <name + rendering model> CHANGES APPLIED: [x] <file> — <what was changed> [x] <file> — <what was changed> ...

If you can't determine the right text, add a placeholder with a `` comment. - **Preserve existing valid SEO.** If a meta tag is already correct, don't rewrite it. - **Flag SPA limitations.** If the project is a client-side SPA with no SSR, explicitly warn that SEO will be severely limited regardless of meta tag fixes. - **No external service calls.** Don't curl APIs, don't fetch competitor pages. Work with the local codebase only. - **One `<h1>` per page.** If you find multiple, fix the hierarchy. - **JSON-LD over microdata.** Prefer `application/ld+json` script blocks. They're easier to maintain and don't pollute HTML.
